Haley Farm State Park in Groton, Connecticut preserves 267 acres of former Colonial-era farmland as open space for non-motorized recreation. Its recorded history begins in 1649 as part of a grant to John Winthrop Jr., and the tract later became Fort Hill Farm before Caleb Haley bought 400 acres in 1869. Haley shaped much of the landscape remembered today, farming the land, building stone walls, and using Racetrack Pond for horse racing. After the farm left the Haley family, development pressure threatened the property, but preservation efforts led to state acquisition beginning in 1970. Today it links local agricultural history with protected coastal and inland habitats and public walking and bicycling.
